Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 133,300,315, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 133,300,315 | |
| -1 | -133,300,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 133,300,315.
Example:
1 x 133,300,315 = 133,300,315
and
-1 x -133,300,315 = 133,300,315
Notice both answers equal 133,300,315
With that explanation out of the way, let's continue. Next, we take the number 133,300,315 and divide it by 2:
133,300,315 ÷ 2 = 66,650,157.5
If the quotient is a whole number, then 2 and 66,650,157.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 133,300,315 | |
| -1 | -133,300,315 |
Now, we try dividing 133,300,315 by 3:
133,300,315 ÷ 3 = 44,433,438.3333
If the quotient is a whole number, then 3 and 44,433,438.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 133,300,315 | |
| -1 | -133,300,315 |
Let's try dividing by 4:
133,300,315 ÷ 4 = 33,325,078.75
If the quotient is a whole number, then 4 and 33,325,078.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 133,300,315 | |
| -1 | 133,300,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 137 | 685 | 2,329 | 11,447 | 11,645 | 57,235 | 194,599 | 972,995 | 1,568,239 | 7,841,195 | 26,660,063 | 133,300,315 |
| -1 | -5 | -17 | -85 | -137 | -685 | -2,329 | -11,447 | -11,645 | -57,235 | -194,599 | -972,995 | -1,568,239 | -7,841,195 | -26,660,063 | -133,300,315 |
